Printing issues and access

Since downloading the lates update to Acrobat 10, I cannot print any PDF.  I can print any other document.  The messages I receive are: Document cannot be printed.  No pages are selected.  The second sentence is not true.

Acrobat has an admin shield on it, and I am asked to "allow" it every time I open it.  I am an admin on my own computer.

Thanks.
